Rolling VS Chipping in Knives! Follow Up Video/440C Test Update
Published: 1 week ago
Clarification I forgot to include in the video:
440C is an ingot steel as is Nitro-V, AEB-L, 14C28N etc. On paper, 440C actually scores a 4.5 in edge retention, while Nitro-V only scores a 3. However, 440C scores a 3.5 in toughness, while Nitro-V scores a 7.5, and AEB-L/14C28N score a whopping 9! The reason I think people believe Nitro-V and it’s family to perform “better” in cutting tasks, is because the high toughness deflects damage so well. People know the Nitro-V family for extreme edge stability and grain refinement. That DOES lead to improved cutting performance even when damage is sustained, if the toughness and microstructure basically still keep that apex stable. 440C in theory, being less tough, could potentially poorly perform via “edge retention”, if damage is sustained. The point in me comparing them wasn’t to go off the papers (because yes we know 440C outcuts Nitro-V in CATRA). It was to show that in real world use, I believe 440C can possibly have edge stability slightly comparable to the Nitro-V family- resulting in enhanced cutting over all. Hopefully that helps. Edge damage=less cutting time. Edge damage is more likely, with lower toughness/larger carbides (especially large chromium carbides). See how it correlates?
